Apiarium vs OpenRouter vs Portkey

Three different answers to the same problem: too many AI provider accounts. Here's how Apiarium compares to OpenRouter and Portkey, and which one actually fits what you're building.

OpenRouter and Portkey are both strong, mature products — this isn't about one being "better" across the board. OpenRouter's strength is model breadth (300+ models, pass-through pricing). Portkey's strength is production-grade observability and governance for teams that need it. Apiarium takes a narrower, simpler angle: one API key, predictable credit-based pricing, and text, image, speech, and transcription covered out of the box — built for indie developers, freelancers, and small teams who want one bill and one integration, not a platform to configure.

Why developers choose Apiarium

🧩

Text, image, speech, transcription

One key, four endpoints. OpenRouter and Portkey are both built around text models — for anything else you're back to separate provider accounts.

🧾

Predictable pricing

Credits map to real usage across every endpoint. No pass-through markup fees or per-log billing to model out ahead of time.

Nothing to configure

No routing rules, no gateway config, no observability dashboard to set up. Sign up and make your first request.

"Partial" on Portkey's managed cloud reflects that it offers both a fully-managed tier and a separate self-hosted open-source gateway — the infrastructure burden depends on which you choose.

When to choose which

Choose OpenRouter if...

You want access to the widest possible catalog of text models — including free and niche open-source ones — and you're comparing models more than building a specific product.

Choose Portkey if...

You're running AI in production at a team/company level and need audit logs, budgets, RBAC, and compliance certifications — and you're willing to configure a gateway to get them.

Choose Apiarium if...

You want one key, one predictable bill, and text, image, speech, and transcription covered — without configuring routing rules or an observability stack first.

What is OpenRouter?

OpenRouter is a unified API gateway giving access to 300+ AI models from 60+ providers through a single, OpenAI-compatible endpoint. It's pay-as-you-go with pass-through pricing plus a credit purchase fee, and includes dozens of free models with rate limits — a popular choice for developers who want to experiment across many models without managing separate provider accounts.

What is Portkey?

Portkey is a production AI gateway focused on observability and governance — routing, fallbacks, semantic caching, guardrails, and detailed logs for cost, latency, and errors across 250+ providers. Its gateway is open source and self-hostable, with a managed cloud tier for teams that want the hosted dashboard and compliance certifications without running it themselves.

Frequently asked questions

Is Apiarium trying to replace OpenRouter or Portkey?

No — they solve different problems well. OpenRouter is the better choice for model breadth. Portkey is the better choice for enterprise observability and governance. Apiarium is for developers who want a simpler, multimodal alternative without configuring either.

Does Apiarium support image, speech, and transcription like OpenRouter or Portkey?

Apiarium does — /llm, /image, /tts, and /transcribe are all included under one key. OpenRouter and Portkey are both primarily built around text/LLM routing.

Can I migrate from OpenRouter or Portkey to Apiarium?

Yes. Apiarium uses its own REST endpoints (documented at apiarium.dev/docs) rather than mimicking the OpenAI format, so migrating means pointing requests at Apiarium's endpoints instead of a drop-in base_url swap.

Is there a free tier?

Yes — 500 free credits to start, no credit card required.
